The following table shows the energy content (in kJ per 100 g) of some common foods. The columns A, B, C and D show the percentage of either protein, fat, carbohydrate or water in each food. Food Energy(kJ/100g) A(%) B(%) C(%) D(%) Milk 290 3 89 4.5 3.5 Butter 3000 0.5 16.5 _ 83 Potatoes 370 2 82 16 _ Tuna 700 18 70 _ 12 Which food has the highest energy content?

Energy is the ability for doing work. Fats provide us energy. Butter is the source of saturated fats. In this table, butter has the highest energy content. It releases 3000 kJ/100 g energy.

The following table shows the energy content (in kJ per 100 g) of some common foods. Columns A, B, C and D show the percentage of either protein, fat, carbohydrate or water in each food. Food Energy(kJ/100g) A(%) B(%) C(%) D(%) Milk 290 3 89 4.5 3.5 Butter 3000 0.5 16.5 _ 83 Potatoes 370 2 82 16 _ Tuna 700 18 70 _ 12 Which food has the lowest energy content?

Energy is the ability for doing work. In the table, milk has the lowest energy content i.e. 290 kJ/100g which is lesser in comparision to Butter, Potatoes and Tuna. Milk is one of the sources of fat, vitamins and minerals and water. It provides strength to bones and teeth.

The following table shows the energy content (in kJ per 100 g) of some common foods. The columns A, B, C and D show the percentage of either protein, fat, carbohydrate or water in each food. Food Energy(kJ/100g) A(%) B(%) C(%) D(%) Milk 290 3 89 4.5 3.5 Butter 3000 0.5 16.5 _ 83 Potatoes 370 2 82 16 _ Tuna 700 18 70 _ 12 Look carefully at the figures and try to work out which of A, B, C or D is carbohydrate, which is water, which is protein, and which is fat. For each choice you make, give reasons.

Column A represents protein content as Tuna has a lot of protein in it. In fact, it is more protein-rich than others. Protein helps for muscle fabricating and repairing tissues. Column B represents water content as milk has more water content than others. Almost 70% of our body weight is water. It is an essential food item for our growth. Column C represents carbohydrate content as Potatoes have more carbohydrates than the other items given in the table. Carbohydrates are energy-yielding food items. Column D represents fat content as butter has more fats than all the other items given here.

The following table shows the energy content (in kJ per 100 g) of some common foods. The columns A, B, C and D show the percentage of either protein, fat, carbohydrate or water in each food. Food Energy(kJ/100g) A(%) B(%) C(%) D(%) Milk 290 3 89 4.5 3.5 Butter 3000 0.5 16.5 _ 83 Potatoes 370 2 82 16 _ Tuna 700 18 70 _ 12 Give two important food materials which are not in the table, but are essential for a balanced diet.

A diet that contains an adequate amount of different nutrients required for the healthy functioning of our body is called a balanced diet. Green leafy vegetables and grains are very important for a balanced diet and are not mentioned in the given table.
